GRAPPLE-HOOK.

SFECIFIGATION forming part of Letters Patent No. 791,969, dated June 6,1905.

Driginal application filed October 15, 1904, Serial No. 228,639. Dividedand this application filed December 22, 1904.. Serial No. 238.023.

To (bi/Z whom it may concern:

Be it known that I, WALTER A. WILEY, a citizen of the United States,residing at Seneca, in the county of N emaha and State of Kansas, haveinvented new and useful Improvements in Grapple-Hooks, of which thefollowing is a specification.

This invention relates to grapple-hooks designed in connection withoverhead power to handle telegraph-poles, beams, and otherobjects ofgreat length and weight.

The subject-matter of my present invention, while particularly designedfor use in connection with the derrick forming the subject-matter of mypending application for United States Betters Patent, filed October 15,1904, Serial No. 228,639, of which this application for patent is adivision, is applicable for use in connection with other overheadhoists, as will be readily understood.

The object of the invention is to provide a light portable grapple-hookto grasp and hold a long heavy pole or beam intermediate its ends whilepower is applied from overhead to move said pole or beam to a desiredposition.

With this object in view the invention will be described in detail inthe ensuing specification and claimed in the clauses at the close.

In the accompanying drawings, Figure 1 is a side elevation of my hookshown in position against a derrick-mast. Fig. 2 is a similar view, theparts being in another position. Fig. 3 is a bottom plan view of thehook. Fig. i is a plan showing a modified form of hook.

The hook comprises a shank A and curved beak B to receive thetelegraph-pole, beam, or other object to be handled.

At the base or heel of the bill B of the hook are arms C, one on eitherside of the bill, their forward ends-that is to say, the ends nearestthe point of the bill-being carried below the body of the bill andshaped to form hooks c, curving rearwardly from the point of the bill,the two constituting jaws to engage the links of a chain to be presentlyfurther referred to. The rear ends of the arms C are spread apart andprovided with bearings in which is journaled the shaft of a roll G. Theshank at its upper end is adapted for connection with a hoist-cable 1,which may be actuated from any source, but in the instance shown istrained over pulley 2 at the top of the mast 3 of the derrick of mypending application, hereinbefore referred to. To the upper end of theshank A is also secured one end of a chain D, the free end being of alength and designed to embrace a pole or beam lodged on the bill of thehook, and passing beneath the same, engage the jaws formed by thedownward hooked projections c of the arms C, thus securely confining thepost or beam and relieving both the bill and shank of the hook fromstrain.

The rear ends of the arms 0 extend somewhat beyond the roll C, thepurpose being to form guides to embrace the sides of the mast 3 whilethe roll C travels in contact with the face thereof to reduce friction.The preferred form of book is shown in Figs. 1 and 2, wherein anL-shaped bracket E is pivoted to the upper end of the shank of the hook.At the angle of the bracket is journaled a pulley 0 for the cable 1 ofthe hoist, said cable being secured in the instance shown near the topof the mast 3, thus reducing resistance between weight and power. Inthis form also the chain 1). is attached to the free end of the bracketE, the purpose being to shift the pulley e from the axial line of theshank A, Fig. 1, to approximately more near the center of gravity of thedevice when the hook is loaded, the chain of course sustaining a part ofthe weight that would otherwise be carried by the shank and bill of thehook. This arrangement enables me to use much lighter hooks for thegiven load and has the further advantage that the cable (usually rope)is held out of frictional contact with the mast 3, thus increasing thelife or usefulness of agiven cable.

In the instance shown the arms C, for convenience of manufacture, areseparate parts bolted to the heel of the bill B of the hook; but it willbe understood that these parts may be made integral and that otherchanges in structure familiar to mechanics are within the scope of myinvention.

1 clain 1. A grapple-hook for pole-raising and similar machines,comprising a shank adapted for connection at its upper end with a hoist,a bill having arms forming jaws, and a chain secured at one end to thetop of the shank and adapted to engage the jaws.

2. A grapple-hook for pole-raising and similar machines, comprising ashank adapted for connection at its upper end with a hoist, a billhaving arms forming jaws at the forward end and carrying a friction-rollat rear, and a chain secured at one end to the top of the shank andadapted to engage the jaws.

3. A grapple-hook for poleraising machines, comprising a shank and abill carrying jaws, an L-shaped bracket pivoted at the upbracket andadapted to engage the jaws of the bill.

In testimony whereof I aflix my signature in presence of two subscribingwitnesses.
